Kayfun Nano drill out bit size

[Cabusi]

Ordred a ehpro kayfun nano. I've already made up my mind to drill out the inlet hole (not the center pin canal). Any suggestions on drill bit size? I want a looser draw than normal. Currently, I'm a heavy lung hitter primarily using a Zenith V2 wide open. Thanks in advance.

have you tried a wider bore driptip?

I'm using a Vapelyfe drip trip. Its faily wide.

I don't have any suggestions as far as drilling out, but I'm curious about this as well. I just got my EHPro KFL+ clone two days ago, and while I do like the flavor and vapor, the airhole whistles when I draw on it. Has anyone found a way to eliminate the whistle? I was considering drilling out the airhole to see if that helps. I'm afraid that if I can't figure it out, my wife may banish my vaping to the garage in short order...
